If you lie about what you're selling, then that's fraud.

Um, yes. It doesn't have to be fraud to be wrong.

But my point is that in the snake-oil analogy, the only reason it's wrong is because the salesperson lies about the benefits of the oil.

The PUA is lying about the benefits of sleeping with them.

What benefits are PUAs supposedly promising and not delivering on?

So, what precisely is the snake oil as it relates to PUAs meeting women?

You.

To be more specific if snake oil really did solve the world's problems snake oil salesmen would still be snake oil salesmen. They are trying to get something by convincing others of a thing whether or not it is true.

So you have a problem with salesmen in general?

Maybe? Anyways I'm mostly commenting on what others may perceive. This is the best explanation I can come up with. I'd honestly rather judge actions based on what happens rather than what was intended to happen. Even if the attitude pisses me off.

That giving the PUA what they want will make them happier.

What specifically do you find evil?
